Help! Sweat probs.

Gabrielle

I'm a sweaty person generally, but lately I'm now getting red rashes on my armpits. It's so uncomfortable! It happens during the work day even when I'm not running around. I use natural deodorant and not antiperspirant, but am looking for any suggestions of ways to calm this down. Could it be a heat rash since it's getting warmer lately? I'm currently stuffing paper towels under my shirt, so help a girl out!
